Title: Roger D Cannell: Innovator in Torque Limiting Control
Introduction
Roger D Cannell is a notable inventor based in Nevada, Iowa, who has made significant contributions to the field of hydraulic systems. He is recognized for his innovative approach to torque limiting control, which enhances the efficiency and safety of hydraulic pumps.
Latest Patents
Roger D Cannell holds a patent for a torque limiting control system designed for a pair of variable displacement hydraulic pumps. This invention features displacement varying means and servo means, which include springs that urge each displacement varying means to a position for maximum pump displacement. The system utilizes fluid-operated means that act in opposition to the springs to adjust the displacement for reduced pump output. The control mechanism sums the fluid pressures generated by both pumps and regulates the servo means to progressively reduce pump displacement as the combined fluid pressures exceed a predetermined threshold. This innovative design effectively limits the torque required by the pumps, enhancing their operational efficiency.
